Definitions

the invention relates to a system for flushing soil.
the object of the invention is to design a system for flushing soil so that, with a substantially constant consumption of fresh water, a higher degree of cleaning of the soil to be treated is achieved, or with a substantially constant degree of cleaning, the consumption of fresh water is significantly reduced.
FIG. 1 shows a side view of a plant for washing soil in a schematic representation.
the system has a flushing-sieve device 1 with a housing 2.
a floor 3 slightly inclined upwards from the inlet side to the outlet side.
feed 4 for the soil to be treated
outlet 5 for discharging the treated soil via a transport device 6 provided.
the bottom 3 On the output side, the bottom 3 comprises a large-area first screen area 7 with a funnel 9 arranged underneath it leading to a water collecting container 8.
a closed bottom section 10 forming a first water supply area is provided in front of the first screen area.
a fresh water supply line is provided, which has outlet nozzles 12 above the floor, which are directed such that soil located above the floor section 10 is slurried by the impinging water jet.
a second screen area 13 is arranged in front of the bottom section 10 and leads on its underside via a funnel 14 into a collecting container 15.
a closed bottom section 16 forming a second water supply area is provided on the input side.
a second water supply line 17 is arranged, which has nozzles 18 on its underside, which are directed in such a way that with the water to be supplied, the soil supplied to the bottom section is slurried with the water.
the closed floor sections 10 and 16 have, as can be seen from the figure, stair-shaped sections 10 inclined upwards towards the exit. Furthermore, the housing is mounted in the manner indicated by arrow 19 in such a way that it is shaken in the direction of arrow 19 by a vibrating device, not shown. This ensures that the feed tion 4 submitted soil is promoted across the ground to the discharge device 5.
the outlet of the water collecting container 8 is connected to the supply line 17 via a pump 21 and a line 22.
the outlet of the collecting container 15 is connected via a line 23 to a water treatment system, not shown, which feeds the treated water to the supply line 11 again.
the soil to be digested is poured in via feed 4. By shaking and the water supplied via the feed line 17, this is slurried and rinsed. In the subsequent screening area 13, the water contaminated with pollutants is largely separated from the remaining soil. A further slurrying of the soil, which is now much less polluted, with fresh water takes place in the subsequent floor area 10. In the first sieve area on the outlet side, the polluted water is separated from the cleaned soil. The cleaned soil is discharged via the discharge device 5. Since the fresh water in the area 10 only comes into contact with the already pre-cleaned soil, it is significantly less polluted than the water flowing out of the collecting container 15. However, it is still very suitable to exclude the much more polluted soil in the previous area Slurry of the soil to be treated to be used and is therefore added to this section.
the bottom sections have a surface shape which is sawtooth-shaped in a vertical section extending in the conveying direction from the inlet 4 to the outlet 5, the flat rise of the saw teeth each inclining towards the inlet side and the steep one Waste is inclined to the output side.
the soil is moved over the flat rise and falls at the edge of the steep descent, thereby avoiding solidification and improving the slurry.
